单向冲洗式气囊导尿管的临床应用与分析

Clinical usage and analysis of the one-way washing air-bulb urinary catheter

目的 :观察应用单向冲洗式气囊导尿管预防留置尿管伴随性尿路感染的临床效果。方法 :随机将瘫痪并尿潴留病人分为 2组 ,实验组 5 0例采用单向冲洗式导尿管 ,用 1/ 5 0 0 0呋喃西林液 5 0 0ml小量持续膀胱冲洗 ;对照组 4 6例采用普通三腔气囊导尿管 ,用 1/ 5 0 0 0呋喃西林液 5 0 0ml小量持续膀胱冲洗。分别在留置尿管的第 3、5、7、10天和拔尿管前进行尿液细菌培养 ,并对拔除导尿管后的气囊头进行细菌培养。结果 :留置尿管后的第 7、10天和拔管前尿液细菌培养以及拔除导尿管后的气囊头细菌培养 ,实验组阳性率明显低于对照组 (χ2 =7.33,P <0 .0 0 1;χ2 =7.92 ,P <0 .0 0 5 ;χ2 =11.16 ,P <0 .0 0 5 ;χ2 =11.16 ,P <0 .0 0 5 )。结论 :使用单向冲洗式气囊导尿管并进行小量持续膀胱冲洗 ,预防尿路感染的效果优于普通三腔气囊导尿管。

Objective:To observe the clinical effect of one-way flow urinary catheter on preventing secondary urinary tract infection. Method : The patients with physical paralysis and bladder urine retention were randomly divided into two groups ,one-way flow urinary catheter with small amount solution (500ml 1/5000 Furacillin )continuously washing bladder of 50 cases as a trial group and routine three cavities air-bulb urinary catheter of 46 cases as a control group. In the trial group urine of 3, 5, 7, 10 day's and before pulling out of retained catheter and the tip of air-bulb catheter after withdrawal were used for bacteria cultures respectively.Result:The positive rates of bacteria cultures in the 7, 10 day's and before pulling out of retained catheter urines and air-bulb tip in trial group were significantly higher than those in control group( χ 2=7.33,P<0.001 ; χ 2=7.92,P<0.005;χ 2=11.16, P<0.005; χ 2=11.16, P <0.005). Conclusion : The effectiveness of small amount solution continuously washing bladder with one-way flow urinary catheter on prevent urinary tract infection is superior than routine three cavities air-bulb urinary catheter.
